passive release mechanism and support for PCI 2.1 compliant delayed transactions.
AGP VGA
INTERFACE (NOT
The 69000 HiQVideo video/graphic accelerator is an Accelerated Graphics Port (AGP)
device. AGP is designed to off-load the PCI Bus by allowing graphics data to move
directly from system memory. The 69000 integrates 2MB of high-speed SDRAM frame
buffer memory into the chip.
AVAILABLE ON
BASIC MODELS)
By embedding SDRAM and graphics controller logic on the same die, the 69000 delivers
uncompromising performance. The increase in the frame buffer bandwidth enables the
69000 to support high-color, high-resolution graphics modes and real-time video acceleration. The interface supports pixel resolutions up to 1600 x 1200 non-interlaced.
Software drivers for enhanced performance and resolution are available for most popular
operating systems.
SYSTEM
HARDWARE
MONITOR
The system hardware monitoring system monitors system voltages, temperature and fan
speeds.
The circuitry is based on National Semiconductor's LM80. The LM80 monitors seven
system voltages, two fan speeds and the board ambient temperature. All of the voltages,
fan speeds and temperature measurements have associated programmable watchdog
limits. When any of these programmed limits are exceeded, the monitor software can be
used to notify the SBC. In addition, the externally available OS# signal can be used to
notify external hardware of any over-temperature condition.
Fan speed monitoring can be configured to monitor two system fans.

INTERFACE (DUAL)
Dual high performance PCI Bus Master EIDE interfaces are capable of supporting two
IDE Type 4 disk drives each in a master/slave configuration. The interface supports
Ultra DMA/33 with synchronous DMA mode transfers up to 33MB per second.
FLOPPY DRIVE
INTERFACE
The SBC supports two floppy disk drives. Drives can be 360K to 2.88MB, in any
combination.
SERIAL INTERFACE
Two high-speed FIFO (16C550) serial ports with independently programmable baud
rates are supported. The IRQ for each serial port has BIOS selectable addressing.
ENHANCED
PARALLEL
INTERFACE
The SBC provides a PC/AT compatible bidirectional parallel port and supports enhanced
parallel port (EPP) mode and extended capabilities port (ECP) mode. The ECP mode is
IEEE 1284 compliant. The IRQ for the parallel port has BIOS selectable addressing.
PS/2 MOUSE
INTERFACE
The SBC is compatible with a PS/2-type mouse. The mouse connection can be made by
using either the PS/2 mouse header or the bracket mounted PS/2 mouse mini DIN
connector. Mouse voltage is protected by a self-resetting fuse.
KEYBOARD
INTERFACE
The SBC is compatible with an AT-type keyboard. The keyboard connection can be
made by using either the keyboard header or the bracket mounted keyboard mini DIN
connector. Keyboard voltage is protected by a self-resetting fuse.
WATCHDOG TIMER
The watchdog timer is a hardware timer which resets the SBC if the timer is not
refreshed by software periodically. The timer is typically used to restart a system in
which an application becomes hung on an external event. When the application is hung,
it no longer refreshes the timer. The watchdog timer then times out and resets the SBC.
The watchdog timer has two levels of enable. First, the watchdog timer jumper must be
moved to the "enabled" position, which puts the watchdog timer under software control.
The second level involves software control of the watchdog's timer retriggering. Bit 6 of
the 82371EB GPOREG register at I/O address 437H must be set to a zero (0), which
blocks the triggering clock to the watchdog timer circuit, thus scheduling a hardware
reset in about 1.5 seconds.
To refresh the watchdog timer, the software in the application toggles bit 6 of the
GPOREG register. First the bit must be set to a one (1) to clear the watchdog timer
delay; then it must be set to a zero (0), which schedules a system reset in 1.5 seconds.
Toggling bit 6 of the GPOREG must occur within a period of less than 1.5 seconds to
insure that a system reset is not issued.
A set of watchdog timer software code and sample programs are available from
Technical Support.
POWER FAIL
DETECTION
Chassis Plans
A hardware reset is issued when on-board +5V voltage drops below 4.75 volts. In

ISA BUS SIGNAL
DESCRIPTIONS
ISA/PCI Reference
The following is a description of the ISA Bus signals. All signal lines are TTLcompatible.
AEN (O)
Address Enable (AEN) is used to degate the microprocessor and other devices from the I/O
channel to allow DMA transfers to take place. When this line is active, the DMA controller has
control of the address bus, the data-bus Read command lines (memory and I/O), and the Write
command lines (memory and I/O).
BALE (O) (Buffered)
Address Latch Enable (BALE) is provided by the bus controller and is used on the system board
to latch valid addresses and memory decodes from the microprocessor. It is available to the I/O
channel as an indicator of a valid microprocessor or DMA address (when used with AEN).
Microprocessor addresses SA[19::0] are latched with the falling edge of BALE. BALE is forced
high during DMA cycles.
BCLK (O)
BCLK is the system clock. The clock has a 50% duty cycle. This signal should only be used for
synchronization. It is not intended for uses requiring a fixed frequency.
CHRDY (I)
I/O Channel Ready (CHRDY) is pulled low (not ready) by a memory or I/O device to lengthen I/
O or memory cycles. Any slow device using this line should drive it low immediately upon
detecting its valid address and a Read or Write command. Machine cycles are extended by an
integral number of clock cycles. This signal should be held low for no more than 2.5 microseconds.
D[15::0] (I/O)
Data signals D[15::0] provide bus bits 15 through 0 for the microprocessor, memory, and I/O
devices. D15 is the most-significant bit and D0 is the least-significant bit. All 8-bit devices on
the I/O channel should use D[7::0] for communications to the microprocessor. The 16-bit
devices will use D[15::0]. To support 8-bit devices, the data on D[15::8] will be gated to D[7::0]
during 8-bit transfers to these devices. 16-bit microprocessor transfers to 8-bit devices will be
converted to two 8-bit transfers.
DAK[7::5]#, DAK[3::0]# (O)
DMA Acknowledge DAK[7::5]# and DAK[3::0]# are used to acknowledge DMA requests
DRQ[7::5] and DRQ[3::0]. They are active low.
DRQ[7::5], DRQ[3::0] (I)
DMA Requests DRQ[7::5] and DRQ[3::0] are asynchronous channel requests used by
peripheral devices and the I/O channel microprocessors to gain DMA service (or control of the
system). They are prioritized, with DRQ0 having the highest priority and DRQ7 having the
lowest. A request is generated by bringing a DRQ line to an active level. A DRQ line must be
held high until the corresponding DMA Request Acknowledge (DAK) line goes active.
DRQ[3::0] will perform 8-bit DMA transfers; DRQ[7::5] will perform 16-bit transfers.
Chassis Plans
2-3
ISA/PCI Reference
CBI/CGI Technical Reference
IO16# (I)
I/O 16-bit Chip Select (IO16#) signals the system board that the present data transfer is a 16-bit,
1 wait-state, I/O cycle. It is derived from an address decode. IO16# is active low and should be
driven with an open collector or tri-state driver capable of sinking 20 mAmps.
IOCHK# (I)
I/O Channel Check (IOCHK#) provides the system board with parity (error) information about
memory or devices on the I/O channel. When this signal is active, it indicates an uncorrectable
system error.
IORC# (I/O)
I/O Read (IORC#) instructs an I/O device to drive its data onto the data bus. It may be driven by
the system microprocessor or DMA controller, or by a microprocessor or DMA controller
resident on the I/O channel. This signal is active low.
IOWC# (I/O)
I/O Write (IOWC#) instructs an I/O device to read the data on the data bus. It may be driven by
any microprocessor or DMA controller in the system. This signal is active low.
IRQ[15::14], IRQ[12::9], IRQ[7::3] (I)
Interrupt Requests IRQ[15::14], IRQ[12::9] and IRQ[7::3] are used to signal the microprocessor
that an I/O device needs attention. The interrupt requests are prioritized, with IRQ[15::14] and
IRQ[12::9] having the highest priority (IRQ9 is the highest) and IRQ[7::3] having the lowest
priority (IRQ7 is the lowest). An interrupt request is generated when an IRQ line is raised from
low to high. The line must be held high until the microprocessor acknowledges the interrupt
request (Interrupt Service routine).
LA[23::17] (I/O)
These signals (unlatched) are used to address memory and I/O devices within the system.
They give the system up to 16MB of addressability. These signals are valid when BALE is high.
LA[23::17] are not latched during microprocessor cycles and therefore do not stay valid for the
whole cycle. Their purpose is to generate memory decodes for 1 wait-state memory cycles.
These decodes should be latched by I/O adapters on the falling edge of BALE. These signals
also may be driven by other microprocessors or DMA controllers that reside on the I/O channel.
M16# (I)
M16# Chip Select signals the system board if the present data transfer is a 1<N>wait-state, 16bit, memory cycle. It must be derived from the decode of LA[23::17]. M16# should be driven
with an open collector or tri-state driver capable of sinking 20 mAmps.
Master16# (I)
Master16# is used with a DRQ line to gain control of the system. A processor or DMA controller
on the I/O channel may issue a DRQ to a DMA channel in cascade mode and receive a DAK#.
Upon receiving the DAK#, an I/O microprocessor may pull Master16# low, which will allow it to
control the system address, data, and control lines (a condition known as tri-state). After
Master16# is low, the I/O microprocessor must wait one system clock period before driving the
address and data lines, and two clock periods before issuing a Read or Write command. If this
signal is held low for more than 15<N>microseconds, system memory may be lost because of a
lack of refresh.
2-4
Chassis Plans
CBI/CGI Technical Reference
ISA/PCI Reference
NOWS# (I)
The No Wait State (NOWS#) signal tells the microprocessor that it can complete the present bus
cycle without inserting any additional wait cycles. In order to run a memory cycle to a 16-bit
device without wait cycles, NOWS# is derived from an address decode gated with a Read or
Write command. In order to run a memory cycle to an 8-bit device with a minimum of two wait
states, NOWS# should be driven active on system clock after the Read or Write command is
active gated with the address decode for the device. Memory Read and Write commands to a
8-bit device are active on the falling edge of the system clock. NOWS# is active low and should
be driven with an open collector or tri-state driver capable of sinking 20 mAmps.
OSC (O)
Oscillator (OSC) is a high-speed clock with a 70-nanosecond period (14.31818 MHz). This
signal is not synchronous with the system clock. It has a 50% duty cycle.
REFRESH# (I/O)
The REFRESH# signal is used to indicate a refresh cycle and can be driven by a microprocessor on the I/O channel.
RESDRV (O)
Reset Drive (RESDRV) is used to reset or initialize system logic at power-up time or during a
low line-voltage outage. This signal is active high.
SA[19::0] (I/O)
Address bits SA[19::0] are used to address memory and I/O devices within the system. These
twenty address lines, in addition to LA[23::17], allow access of up to 16MB of memory.
SA[19::0] are gated on the system bus when BALE is high and are latched on the falling edge of
BALE. These signals are generated by the microprocessor or DMA Controller. They also may
be driven by other microprocessors or DMA controllers that reside on the I/O channel.
SBHE# (I/O)
System Bus High Enable (SBHE#) indicates a transfer of data on the upper byte of the data bus,
D[15::8]. 16-bit devices use SBHE# to condition data bus buffers tied to D[15::8].
SMRDC# (O), MRDC# (I/O)
These signals instruct the memory devices to drive data onto the data bus. SMRDC# is active
only when the memory decode is within the low 1MB of memory space. MRDC# is active on all
memory read cycles. MRDC# may be driven by any microprocessor or DMA controller in the
system. SMRDC is derived from MRDC# and the decode of the low 1MB of memory. When a
microprocessor on the I/O channel wishes to drive MRDC#, it must have the address lines valid
on the bus for one system clock period before driving MRDC# active. Both signals are active
low.
SMWTC# (O), MWTC# (I/O)
These signals instruct the memory devices to store the data present on the data bus. SMWTC#
is active only when the memory decode is within the low 1MB of the memory space. MWTC# is
active on all memory write cycles. MWTC# may be driven by any microprocessor or DMA
controller in the system. SMWTC# is derived from MWTC# and the decode of the low 1MB of
memory. When a microprocessor on the I/O channel wishes to drive MWTC#, it must have the
address lines valid on the bus for one system clock period before driving MWTC# active. Both
signals are active low.

PCI LOCAL BUS
OVERVIEW
CBI/CGI Technical Reference
The PCI (Peripheral Component Interconnect) Local Bus is a high performance, 32-bit or
64-bit bus with multiplexed address and data lines. It is intended for use as an interconnect mechanism between highly integrated peripheral controller components,
peripheral add-in boards and processor/memory systems.
The "local bus" moves peripheral functions with high bandwidth requirements closer to
the system’s processor bus and can produce substantial performance gains with graphical
user interfaces (GUIs) and other high bandwidth functions (i.e., full motion video, SCSI,
LANs, etc.).
The PCI Local Bus accommodates future system requirements and is applicable across
multiple platforms and architectures.
The PCI component and add-in card interface is processor independent, enabling an
efficient transition to future processor generations, by bridges or by direct integration,
and use with multiple processor architectures. Processor independence allows the PCI
Local Bus to be optimized for I/O functions, enables concurrent operation of the local
bus with the processor/memory subsystem, and accommodates multiple high performance peripherals in addition to graphics. Movement to enhanced video and multimedia
displays and other high bandwidth I/O will continue to increase local bus bandwidth
requirements. A transparent 64-bit extension of the 32-bit data and address buses is
defined, doubling the bus bandwidth and offering forward and backward compatibility of
32-bit (132MB/s peak) and 64-bit (264MB/s peak) PCI Local Bus peripherals.

PIN ASSIGNMENTS
ISA/PCI Reference
The PCI Local Bus pin assignments shown below are for the PCI option slots on the
backplane.
The PCI Local Bus specifies both 5-volt and 3.3-volt signaling environments. The
following bus pin assignments are for the 5-volt connector. The 3.3-volt connector bus
pin assignments are the same with the following exceptions:
*
The pins noted as +V (I/O) are +5 volts or +3.3 volts, depending on which
connector is being used.
†
Pins B12, B13, A12 and A13 are Gnd (ground) on the 5-volt connector, but
are Connector Keys on the 3.3-volt connector.
††
Pin B49 is Gnd (ground) on the 5-volt connector, but is M66EN on the 3.3volt connector.
†††
Pins B50, B51, A50 and A51 are Connectors Keys on the 5-volt connector,
but are Gnd (ground) on the 3.3-volt connector.

ISA/PCI Reference
PCI LOCAL BUS
SIGNAL
DESCRIPTIONS
CBI/CGI Technical Reference
The PCI Local Bus signals are described below and may be categorized into the
following functional groups:
•
System Pins
•
Address and Data Pins
•
Interface Control Pins
•
Arbitration Pins (Bus Masters Only)
•
Error Reporting Pins
•
Interrupt Pins (Optional)
•
Cache Support Pins (Optional)
•
64-Bit Bus Extension Pins (Optional)
•
JTAG/Boundary Scan Pins (Optional)
A # symbol at the end of a signal name indicates that the active state occurs when the
signal is at a low voltage. When the # symbol is absent, the signal is active at a high
voltage.
The following are descriptions of the PCI Local Bus signals.
ACK64# (optional)
Acknowledge 64-bit Transfer, when actively driven by the device that has positively decoded its
address as the target of the current access, indicates the target is willing to transfer data using
64bits. ACK64# has the same timing as DEVSEL#.
AD[31::00]
Address and Data are multiplexed on the same PCI pins. A bus transaction consists of an
address phase followed by one or more data phases. During the address phase, AD[31::00]
contain a physical address (32 bits). During data phases, AD[07::00] contain the least significant byte (lsb) and AD[31::24] contain the most significant byte (msb).
AD[63::32] (optional)
Address and Data are multiplexed on the same pins and provide 32additional bits. During an
address phase (when using the DAC command and when REQ64# is asserted), the upper
32bits of a 64-bit address are transferred; otherwise, these bits are reserved but are stable and
indeterminate. During a data phase, an additional 32bits of data are transferred when REQ64#
and ACK64# are both asserted.
C/BE[3::0]#
Bus Command and Byte Enables are multiplexed on the same PCI pins. During the address
phase of a transaction, these pins define the bus command; during the data phase they are
used as byte enables. The byte enables are valid for the entire data phase and determine
which byte lanes carry meaningful data. C/BE0# applies to byte0 (lsb) and C/BE3# applies to
byte 3 (msb).
2-14
Chassis Plans
CBI/CGI Technical Reference
ISA/PCI Reference
C/BE[7::4]# (optional)
Bus Command and Byte Enables are multiplexed on the same pins. During an address phase
(when using the DAC command and when REQ64# is asserted), the actual bus command is
transferred on C/BE[7::4]#; otherwise, these bits are reserved and indeterminate. During a data
phase, C/BE[7::4]# are byte enables indicating which byte lanes carry meaningful data when
REQ64# and ACK64# are both asserted. C/BE4# applies to byte4 and C/BE7# applies to
byte7.
CLK
Clock provides timing for all transactions on PCI and is an input to every PCI device.
DEVSEL#
Device Select, when actively driven, indicates that the driving device has decoded its address
as the target of the current access. As an input, DEVSEL# indicates whether any device on the
bus has been selected.
FRAME#
Cycle Frame is an interface control pin which is driven by the current master to indicate the
beginning and duration of an access. When FRAME# is asserted, data transfers continue;
when it is deasserted, the transaction is in the final data phase.
GNT#
Grant indicates to the agent that access to the bus has been granted. This is a point to point
signal. Every master has its own GNT#.
IDSEL
Initialization Device Select is used as a chip select during configuration read and write transactions.
INTA#, INTB#, INTC#, INTD# (optional)
Interrupts on PCI are optional and defined as "level sensitive," asserted low (negative true),
using open drain output drivers. PCI defines one interrupt for a single function and up to four
interrupt lines for a multi-function device or connector.
Interrupt A is used to request an interrupt. For a single function device, only INTA# may be
used, while the other three interrupt lines have no meaning.
Interrupt B, Interrupt C and Interrupt D are used to request additional interrupts and only have
meaning on a multi-function device.
IRDY#
Initiator Ready indicates the initiating agent’s (bus master’s) ability to complete the current data
phase of the transaction. IRDY# is used in conjunction with TRDY#. During a write, IRDY#
indicates that valid data is present on AD[31::0]. During a read, it indicates that the master is
prepared to accept data.
LOCK#
Lock indicates an operation that may require multiple transactions to complete. When LOCK#
is asserted, non-exclusive transactions may proceed to an address that is not currently locked.
Chassis Plans
2-15
ISA/PCI Reference
CBI/CGI Technical Reference
PAR
Parity is even parity across AD[31::00] and C/BE[3::0]#. Parity generation is required by all PCI
agents. The master drives PAR for address and write data phases; the target drives PAR for
read data phases.
PAR64 (optional)
Parity Upper DWORD is the even parity bit that protects AD[63::32] and C/BE[7::4]#. The
master drives PAR64 for address and write data phases; the target drives PAR64 for read data
phases.
PERR#
Parity Error is for the reporting of data parity errors during all PCI transactions except a Special
Cycle. There are no special conditions when a data parity error may be lost or when reporting
of an error may be delayed.
PRSNT1# and PRSNT2#
PRSNT1# and PRSNT2# are related to the connector only, not to other PCI components. They
are used for two purposes: indicating that a board is physically present in the slot and providing
information about the total power requirements of the board.
REQ#
Request indicates to the arbiter that this agent desires use of the bus. This is a point to point
signal. Every master has its own REQ#.
REQ64# (optional)
Request 64-bit Transfer, when actively driven by the current bus master, indicates it desires to
transfer data using 64 bits. REQ64# has the same timing as FRAME#. REQ64# has meaning
at the end of reset.
RST#
Reset is used to bring PCI-specific registers, sequencers and signals to a consistent state.
SBO# (optional)
Snoop Backoff is an optional cache support pin which indicates a hit to a modified line when
asserted. When SBO# is deasserted and SDONE is asserted, it indicates a "clean" snoop
result.
SDONE (optional)
Snoop Done is an optional cache support pin which indicates the status of the snoop for the
current access. When deasserted, it indicates the result of the snoop is still pending. When
asserted, it indicates the snoop is complete.
SERR#
System Error is for reporting address parity errors, data parity errors on the Special Cycle
command, or any other system error where the result will be catastrophic. If an agent does not
want a non-maskable interrupt (NMI) to be generated, a different reporting mechanism is
required.
2-16
Chassis Plans
CBI/CGI Technical Reference
ISA/PCI Reference
STOP#
Stop indicates that the current target is requesting the master to stop the current transaction.
TCK (optional)
Test Clock is used to clock state information and test data into and out of the device during
operation of the TAP (Test Access Port).
TDI (optional)
Test Data Input is used to serially shift test data and test instructions into the device during TAP
(Test Access Port) operation.
TDO (optional)
Test Data Output is used to serially shift test data and test instructions out of the device during
TAP (Test Access Port) operation.
TMS (optional)
Test Mode Select is used to control the state of the TAP (Test Access Port) controller in the
device.
TRDY#
Target Ready indicates the target agent’s (selected device’s) ability to complete the current data
phase of the transaction. TRDY# is used in conjunction with IRDY#. During a read, TRDY#
indicates that valid data is present on AD[31::00]. During a write, it indicates that the target is
prepared to accept data.
TRST# (optional)
Test Reset provides an asynchronous initialization of the TAP controller. This signal is optional
in the IEEE Standard Test Access Port and Boundary Scan Architecture.

System BIOS
Chapter 3
System BIOS
BIOS OPERATION
Sections 3 through 8 of this manual describe the operation of the American Megatrends
AMIBIOS and the AMIBIOS Setup Utility. Refer to Running AMIBIOS Setup later in
this chapter for standard Setup screens, options and defaults. The available Setup
screens, options and defaults may vary if you have a custom BIOS.
When the system is powered on, AMIBIOS performs the Power-On Self Test (POST)
routines. These routines are divided into two phases:
1) System Test and Initialization. Test and initialize system boards for
normal operations.
2) System Configuration Verification. Compare defined configuration with
hardware actually installed.
If an error is encountered during the diagnostic tests, the error is reported in one of two
different ways. If the error occurs before the display device is initialized, a series of
beeps is transmitted. If the error occurs after the display device is initialized, the error
message is displayed on the screen. See BIOS Errors later in this section for more information on error handling.
The following are some of the Power-On Self Tests (POSTs) which are performed when
the system is powered on:
•
CMOS Checksum Calculation
•
Keyboard Controller Test
•
CMOS Shutdown Register Test
•
8254 Timer Test
•
Memory Refresh Test
•
Display Memory Read/Write Test
•
Display Type Verification
•
Entering Protected Mode
•
Memory Size Calculation
•
Conventional and Extended Memory Test
•
DMA Controller Tests
•
Keyboard Test
• System Configuration Verification and Setup
_______________________________________________________________________
NOTE: When you perform a warm boot by pressing <Ctrl> + <Alt> + <Del>, all
memory tests are bypassed.
_______________________________________________________________________
AMIBIOS checks system and cache memory and reports them on both the initial
AMIBIOS screen and the AMIBIOS System Configuration screen which appears after
POST is completed. AMIBIOS attempts to initialize the peripheral devices by verifying
Chassis Plans

System BIOS
CBI/CGI Technical Reference
the validity of the system setup information stored in the system CMOS RAM. (See
Running AMIBIOS Setup later in this chapter.) If AMIBIOS detects a fault, the screen
displays the error condition(s) which has/have been detected. If no errors are detected,
AMIBIOS attempts to load the system from any bootable device, such as a floppy disk or
hard disk.
Normally, the only POST routine visible on the screen is the memory test. The following
screen displays when the system is powered on:
AMIBIOS (C)1998 American Megatrends Inc.
TRENTON Technology Inc.
Hit DEL if you want to run SETUP
Initial Power-On Screen
You have two options:
•
Press <Del> to access the AMIBIOS Setup Utility.
This option allows you to change various system parameters such as date
and time, disk drives, etc. The Running AMIBIOS Setup section of this
manual describes the options available.
You may be requested to enter a password before gaining access to the
AMIBIOS Setup Utility. (See Password Entry later in this section.)
If you enter the correct password or no password is required, the AMIBIOS
Setup Main Menu displays. (See Running AMIBIOS Setup later in this
section.)
•
Allow the bootup process to continue without invoking the AMIBIOS Setup
Utility.
In this case, after AMIBIOS loads the system, you may be requested to enter
a password. (See Password Entry later in this section.)
Once the POST routines complete successfully, a screen displays showing the current
configuration of your system, including processor type, base and extended memory
amounts, floppy and hard drive types, display type and peripheral ports.
In systems with more than 1MB, AMIBIOS reports 384KB less RAM than it finds,
because it accounts for the address space between 640K and 1024K which is unavailable
to DOS. This space is used for video RAM, video BIOS, system BIOS and adapter
ROMs.

Password Entry
The system may be configured so that the user is required to enter a password each time
the system boots or whenever an attempt is made to enter AMIBIOS Setup. The
password function may also be disabled so that the password prompt does not appear
under any circumstances.
The Password Check option in the Advanced CMOS Setup program allows you to
specify when the password prompt displays: Always or only when Setup is attempted.
The supervisor and user passwords may be changed using the Change Supervisor
Password and Change User Password options on the AMIBIOS Setup Main Menu. If
the passwords are null, the password prompt does not display at any time. A more
detailed description of the password setup function may be found in the Running
AMIBIOS Setup section later in this chapter.
When password checking is enabled, the following password prompt displays:
Enter CURRENT Password:
Type the password and press <Enter>.
_______________________________________________________________________
NOTE: The null password is the system default and is in effect if a password has not
been assigned or if the CMOS has been corrupted. In this case, the password prompt
does not display. To set up passwords, you may use the Change Supervisor Password
and Change User Password options on the AMIBIOS Setup Main Menu. (See Running
AMIBIOS Setup later in this chapter.)
_______________________________________________________________________
If an incorrect password is entered, the following screen displays:
Enter CURRENT Password: X
Enter CURRENT Password:

System BIOS
CBI/CGI Technical Reference
You may try again to enter the correct password. If you enter the password incorrectly
three times, the system responds in one of two different ways, depending on the value
specified in the Password Check option on the Advance CMOS Setup screen:
1) If the Password Check option is set to Setup, the system does not let you
enter Setup, but does continue the booting process. You must reboot the
system manually to retry entering the password.
2) If the Password Check option is set to Always, the system locks and you
must reboot. After rebooting, you will be requested to enter the password.
Once the password has been entered correctly, you are allowed to continue.
BIOS Errors
If an error is encountered during the diagnostic checks performed when the system is
powered on, the error is reported in one of two different ways:
1) If the error occurs before the display device is initialized, a series of beeps is
transmitted.
2) If the error occurs after the display device is initialized, the screen displays
the error message. In the case of a non-fatal error, a prompt to press the
<F1> key may also appear on the screen.
Explanations of the beep codes and BIOS error messages may be found in Appendix A BIOS Messages.
As the POST routines are performed, test codes are presented on Port 80H. These codes
may be helpful as a diagnostic tool and are listed in Appendix A - BIOS Messages.
If certain non-fatal error conditions occur, you are requested to run the AMIBIOS Setup
Utility. The error messages are followed by this screen:

RUNNING
AMIBIOS SETUP
System BIOS
AMIBIOS Setup keeps a record of system parameters, such as date and time, disk drives,
display type and other user-defined parameters. The Setup parameters reside in the Read
Only Memory Basic Input/Output System (ROM BIOS) so that they are available each
time the system is turned on. AMIBIOS Setup stores the information in the complementary metal oxide semiconductor (CMOS) memory. When the system is turned off, a
backup battery retains system parameters in the CMOS memory.
Each time the system is powered on, it is configured with these values, unless the CMOS
has been corrupted or is faulty. The AMIBIOS Setup Utility is resident in the ROM
BIOS so that it is available each time the computer is turned on. If, for some reason, the
CMOS becomes corrupted, the system is configured with the default values stored in this
ROM file.
As soon as the system is turned on, the power-on diagnostic routines check memory,
attempt to prepare peripheral devices for action, and offer you the option of pressing
<Del> to run AMIBIOS Setup.
If certain non-fatal errors occur during the Power-On Self Test (POST) routines which
are run when the system is turned on, you may be prompted to run AMIBIOS Setup by
pressing <F1>.

AUTO-DETECT
HARD DISKS
System BIOS
The Auto-Detect Hard Disks option allows you to have AMIBIOS automatically detect
the type of hard disk drive(s) in your system. The automatic detection functions only if
you have IDE drives. The parameters are reported on the Standard CMOS Setup screen.
AMIBIOS searches first for the primary master and slave hard disk drives, then for the
secondary master and slave drives. If it can access a drive, it reads the disk parameters.
It then searches the AMIBIOS drive type table for matching parameters to determine the
disk type and displays both the type and parameters on the screen. If no matching
parameters are found in the table, AMIBIOS specifies the type as "User" and fills in the
parameter values it found on the drive. If it cannot access the drive or if it is not an IDE
drive, AMIBIOS times out and specifies that the disk drive is "Not Installed."
_______________________________________________________________________
NOTE: The auto detect feature displays disk parameter values as established by the
drive manufacturer. If the drive has been formatted using any other values, accepting the
auto detect values will cause erratic behavior. You must either reformat the drive to meet
the manufacturer's specifications or use Standard CMOS Setup to enter parameters which
match the current format of the drive.
_______________________________________________________________________
If you do not want to accept the hard disk type and its associated parameters as reported
by AMIBIOS or if the drive is "Not Installed," you may use Standard CMOS Setup to set
up the correct parameters for the drive.
Once the parameters are correct for all of the drives, you may exit from the Standard
CMOS Setup screen and save the settings in the CMOS.
CHANGE
PASSWORD
AMIBIOS Setup has an optional password feature which can be configured so that a
password must be entered each time the system boots or just when a user attempts to
enter AMIBIOS Setup. (See the Advanced CMOS Setup section of this manual for information on how to enable the Password Check option.)
The Change Supervisor Password and Change User Password options on the
AMIBIOS Setup Main Menu allow you to establish passwords, change the current
passwords or disable the password prompts by entering null passwords. The passwords
are stored in CMOS RAM.
The Change User Password function is accessible only if the supervisor password has
been established previously. If you have signed on under the user password, you cannot
change the supervisor password.
_______________________________________________________________________
NOTE: The null password is the system default and is in effect if a password has not
been assigned or if the CMOS has been corrupted. In this case, the "Enter CURRENT
Password" prompt is bypassed when you boot the system, and you must establish a new
password.
_______________________________________________________________________
CHANGE
SUPERVISOR
PASSWORD
If you select the Change Supervisor Password option, the following window displays:
Enter new supervisor password: _
Chassis Plans
3-11
System BIOS
CBI/CGI Technical Reference
This is the message which displays before you have established a password or if the last
password entered was the null password. If a password has already been established, you
are asked to enter the current password before being prompted to enter the new
password.
Type the new password and press <Enter>. The password cannot exceed six (6)
characters in length. The screen does not display the characters as you type them.
After you have entered the new password, the following window displays:
Retype new supervisor password: _
Re-key the new password as described above.
If the password confirmation is miskeyed, AMIBIOS Setup displays the following
message:
Incorrect password, press any key to continue
No retries are permitted; you must restart the procedure from the AMIBIOS Setup Main
Menu.
If the password confirmation is entered correctly, the following message displays:
New supervisor password installed, press any key to continue
When you press any key, the screen returns to the AMIBIOS Setup Main Menu screen,
which allows you to save the password change or exit from Setup without saving the new
password. To save the new password in CMOS memory, be sure to select Save Settings
and Exit.
If you save the changes when you exit AMIBIOS Setup, the password is stored in CMOS
RAM. The next time the system boots, you are prompted for the password if the
password function is present and is enabled. (See Advanced CMOS Setup later in this
manual for an explanation of how to enable password checking.)
_______________________________________________________________________
NOTE: Be sure to keep a record of the new password each time it is changed. If you
forget it, use the Password Clear jumper to reset it to the default (null password). See the
Specifications chapter of this manual for details.

The Change User Password option is similar in functionality to the Change Supervisor
Password and displays the same messages, except that "user" replaces "supervisor." If
you have signed on under the user password, you cannot change the supervisor
password.
DISABLING THE
PASSWORD(S)
To disable password checking so that the password prompt does not appear under any
circumstances, you may create null passwords using the Change Supervisor Password
and Change User Password functions by pressing <Enter> without typing in a new
password. You will be asked to confirm the password. Select <Enter> again and the
following message displays:
Supervisor password disabled, press any key to continue
When you press any key, the screen returns to the AMIBIOS Setup Main Menu, which
allows you to save the password change or exit from Setup without saving the null
password. To save the null password(s) in CMOS memory, be sure to select Save
Settings and Exit.
AUTO
CONFIGURATION
OPTIONS
Each AMIBIOS Setup option has two default settings (Optimal and Fail Safe). These
settings can be applied to all AMIBIOS Setup options when you select the appropriate
auto configuration option from the AMIBIOS Setup Main Menu.
You can use these auto configuration options to quickly set the system configuration
parameters which should provide the best performance characteristics, or you can select
a group of settings which have a better chance of working when the system is having
configuration-related problems.
Auto Configuration with Optimal Settings
This option allows you to load the Optimal default settings. These settings are best-case
values which should provide the best performance characteristics. If CMOS RAM is
corrupted, the Optimal settings are loaded automatically.
If you select the Auto Configuration with Optimal Settings option, the following
window displays:

The AMIBIOS enhanced IDE (EIDE) interface can support IDE Type 4 disk drives.
This EIDE interface allows disk drives greater than 528MB to be used.
The hard disk drives can be detected automatically by AMIBIOS (if they are IDE drives)
or can be defined manually by the user, as described below.

To set up the hard disk drive parameter(s), use the plus (+) key or PgDn key to scroll
through the drive types to locate the correct type of disk drive(s) in your computer.
As you scroll through the disk types, the drive Type displays, along with values for size,
cylinders, heads, write precompensation and sectors. Available predefined hard disk
drive types are listed at the end of this section. If the parameters supplied by the
manufacturer of your disk drive do not match any of these preprogrammed drive types,
you may have AMIBIOS detect the drive type automatically (if it is an IDE drive), or
you may select the User drive type to enter the parameters manually as described below.
Set the drive type to CD-ROM to boot from a CD-ROM drive.
Not Installed is available for use as an option. This option can be used for diskless work
stations.
Automatic Detection of Drive Type
If any of the hard disks are IDE drives, AMIBIOS can automatically configure the drive
type by detecting the IDE drive parameters and reporting them on the Standard CMOS
Setup screen.
You may invoke automatic detection of IDE drives in one of three ways:
•
Chassis Plans
Press Enter when the cursor is in the Type field. AMIBIOS detects the
drive type and parameters as requested. If the drive type is not defined in
the drive type table, this option displays User as the drive type and displays
the parameters which were detected by AMIBIOS. The detected drive type
values may then be saved in the CMOS.
4-3
Standard CMOS Setup
CBI/CGI Technical Reference
•
Set the drive type to Auto to have AMIBIOS detect the drive type and
parameters automatically each time the system is booted up. This option
does not display the drive type on the Standard CMOS Setup screen, but
does display it on the System Configuration screen shown after a successful
bootup.
•
Select the Auto-Detect Hard Disks option on the AMIBIOS Setup Main
Menu to have AMIBIOS automatically detect the type and parameters of
each hard drive and place the information into the Standard CMOS Setup
screen. The detected drive type values may then be saved in the CMOS.
This option is described in the Running AMIBIOS Setup section of the
System BIOS chapter of this manual.
_______________________________________________________________________
NOTE: The auto detect feature displays disk parameter values as established by the
drive manufacturer. If the drive has been formatted using any other values, accepting the
auto detect values will cause erratic behavior. You must either reformat the drive to meet
the manufacturer's specifications or use the User type to enter parameters which match
the current format of the drive.
_______________________________________________________________________
User-Defined Drive Types
If the parameters supplied by the manufacturer of your disk drive do not match any of the
preprogrammed drive types provided by AMIBIOS, you may enter the parameters
manually.
The user-defined parameters for each of the four drives may be different, which effectively allows four different user-definable hard disk types.
Scroll to the end of the drive type list to the User type. You can manually enter the Cyln,
Head, WPcom and Sec parameters. The Size parameter is automatically calculated and
displayed by the system based on the other parameters entered.
Use the arrow keys or tab key to move between fields. Once you have placed the cursor
in a field, type in the correct value.
The following explains the drive parameters which you must enter for a drive type which
is not in the list:
Type is the numeric designation for a drive with certain identification parameters.
Cylinders (Cyln) is the number of disk cylinders found in the specified drive
type.
Heads (Head) is the number of disk heads found in the specified drive type.
Write Precompensation (WPcom) is the read delay circuitry which takes into
account the timing differences between the inner and outer edges of the surface
of the disk. The size of the sector gets progressively smaller as the track
diameter diminishes. Yet each sector must still hold 512 bytes. Write precompensation circuitry on the hard disk compensates for the physical difference in
4-4
Chassis Plans
CBI/CGI Technical Reference
Standard CMOS Setup
sector size by boosting the write current for sectors on inner tracks. This
parameter designates the track (cylinder) number where write precompensation
begins.
Sectors (Sec) designates the number of disk sectors per track.
Size is the formatted capacity of the drive (in megabytes) based on the following
formula:
# of heads x # of cylinders x # of sects/cyln x 512 bytes/sect
IDE Drive Type Setup Options
For each of the four hard disk drives which is an IDE drive, the following options are
also available for the drive:
Logical Block Addressing (LBA) Mode
This option allows you to enable IDE LBA (Logical Block Addressing) Mode for the
specified primary or secondary IDE drive. Data is accessed by block addresses rather
than by the traditional cylinder-head-sector format. This allows you to use drives larger
than 528MB.
If LBA Mode is set to On and is supported by the hard disk drive, and if the drive is
formatted, AMIBIOS enables LBA mode and translates the physical parameters of the
drive to logical parameters. If a hard disk drive which supports LBA mode and has a
capacity greater than 528MB was formatted with LBA mode disabled, AMIBIOS does
not enable LBA mode even if the LBA Mode parameter is set to On in Standard CMOS
Setup.
If LBA Mode is set to Off, AMIBIOS uses the physical parameters of the hard disk and
does not translate parameters. The operating system which uses the parameter table then
sees only 528MB of hard disk space even if the drive contains more than 528MB.
Available options are:
Off
On
Block (Blk) Mode
This option supports transfer of multiple sectors to and from the specified primary or
secondary IDE drive.
Block mode boosts IDE drive performance by increasing the amount of data transferred
during an interrupt. Block mode allows transfers of up to 64KB per interrupt, whereas
only 512 bytes of data can be transferred per interrupt if block mode is not used.
If Block Mode is set to On and is supported by the IDE drive, AMIBIOS enables multisector transfers. AMIBIOS sets the number of sectors to be transferred per interrupt to
the value returned by the "identify drive" command.

Programmed I/O (PIO) Mode
IDE PIO mode programs timing cycles between the IDE drive and the programmable
IDE controller. As the PIO mode increases, the cycle time decreases.
Set the PIO Mode option to Auto to have AMIBIOS select the PIO mode used by the
IDE drive being configured. If you select a specific value for the PIO mode, you must
make absolutely certain that you are selecting the PIO mode supported by the IDE drive
being configured.

32Bit Mode
Hard disk drives connected to the SBC via the ISA Bus transfer data 16 bits at a time.
An IDE drive on the PCI Local Bus can use a 32-bit data path.
If the 32Bit Mode parameter is set to On, AMIBIOS enables 32-bit data transfers. If the
host controller does not support 32-bit transfer, this feature must be disabled.

Select ‘Y’ or ‘N’ as appropriate. You may have to select ‘N’ several times to prevent the
boot sector write.
The following message displays if any attempt is made to format any cylinder, head or
sector of any hard disk drive via the BIOS INT 13 Hard Disk Drive Service:
Format!!! Possible VIRUS: Continue (Y/N)?
Select ‘Y’ or ‘N’ as appropriate. If you select ‘Y’ to continue, formatting proceeds
normally. If you do not want to continue formatting, you may have to select ‘N’ several
times, depending on how many retries are performed by the upper-level software. For
example, DOS does at least five retries before the Format utility is actually terminated.
_______________________________________________________________________
NOTE: You should not enable boot sector virus protection when formatting a hard
drive.
_______________________________________________________________________
The DOS hard disk Format utility does not use INT 13H function AH=05H to format the
hard disk. It only verifies the hard disk using the INT 13H Verify function (AH=04H).
The virus warning message is not displayed during DOS hard disk drive formatting.

Quick Boot
This option allows you to have the AMIBIOS boot quickly when the computer is
powered on or go through more complete testing.
When this option is set to Disabled, AMIBIOS tests all system memory. It waits up to
40 seconds for a READY signal from the IDE hard disk drive. It waits for .5 seconds
after sending a RESET signal to the IDE drive to allow the drive time to get ready again.
It also checks whether the user has pressed the <Del> key and runs the AMIBIOS Setup
program if the key has been pressed.
If the option is set to Enabled, AMIBIOS checks only the first 1MB of system memory.
It does not wait up to 40 seconds for a READY signal from the IDE hard disk drive. If a
READY signal is not received immediately, AMIBIOS does not configure the drive. It
does not wait for .5 seconds after sending a RESET signal to the IDE drive to allow the
IDE drive time to get ready again.
If you have set your system up for a quick boot, you cannot run AMIBIOS Setup at
system boot, because there is no delay for the "Hit DEL if you want to run SETUP"
message.

AMIBIOS configures the on-board serial ports to avoid conflicts.
AMIBIOS checks the ISA Bus for serial ports. Any off-board serial ports found on the
ISA Bus are left at their assigned addresses. Serial Port 1, the first on-board serial port,
is configured with the first available address and Serial Port 2, the second on-board serial
port, is configured with the next available address. The default address assignment order
is 3F8H, 2F8H, 3E8H, 2E8H. Note that this same assignment order is used by
AMIBIOS to place the active serial port addresses in lower memory (BIOS data area) for
configuration as logical COM devices.
After all addresses have been assigned, any remaining on-board serial ports are disabled.

on-board Parallel Port is automatically configured with the first available address not
used by an off-board parallel port. The default address assignment order is 3BCH, 378H,
278H. Note that this same assignment order is used by AMIBIOS to place the active
parallel port addresses in lower memory (BIOS data area) for configuration as logical
LPT devices.

BIOS Messages
BIOS BEEP CODES
Errors may occur during the POST (Power-On Self Test) routines which are performed
each time the system is powered on.
Non-fatal errors are those which, in most cases, allow the system to continue the bootup
process. The error message normally appears on the screen. See BIOS Error Messages
later in this appendix for descriptions of these messages.
Fatal errors are those which will not allow the system to continue the bootup procedure.
These fatal errors are usually communicated through a series of audible beeps. Each
error message has its own specific beep code, defined by the number of beeps following
the error detection. The following table lists the errors which are communicated audibly.
All errors listed, with the exception of #8, are fatal errors.

Host Adapter SCSI ID
Each device on the SCSI bus, including the adapter, must have a unique SCSI ID.
Allowable IDs are 0 through 7 on 8-bit adapters, and 0 through 15 on 16-bit adapters.
The SCSI ID serves two purposes:
1) It uniquely defines each SCSI device on the bus.
2) It determines which device controls the bus when two or more devices try to
use the bus at the same time. For 8-bit devices, SCSI ID 7 has the highest
C-4
Chassis Plans
CBI/CGI Technical Reference
priority and SCSI ID 0 has the lowest priority. For 16-bit devices, the
priority of IDs is 7 through 0, then 15 through 8,with SCSI ID 7 having the
highest priority and SCSI ID 8 having the lowest priority.
All adapters (8-bit and 16-bit) have a default SCSI ID of 7, which gives the host adapter
the highest priority on the SCSI bus.
Available options are:
8-bit Adapters:
0 through 7
16-bit Adapters:
0 through 15
SCSI Parity Checking
Each adapter uses SCSI parity checking to verify the accuracy of data transfer on the
SCSI bus. By default, parity checking is set to Enabled.
Most currently available SCSI devices support SCSI parity. However, if a device on the
SCSI bus does not support SCSI parity, set the SCSI Parity Checking option to
Disabled.
Available options are:
Enabled
Disabled
Host Adapter SCSI Termination
A set of resistors, called terminators, must be either installed in or enabled on the first
and last SCSI devices on each SCSI bus; otherwise, the devices will not operate properly.
Because the adapter is usually the SCSI device at one end of the bus, adapter termination
for an 8-bit adapter is set to Enabled by default. If an 8-bit adapter is not at the end of
the SCSI bus, set the Host Adapter SCSI Termination option to Disabled.

SCSI Device Configuration Screen
The SCSI Device Configuration screen lists the current device settings for each SCSI ID,
even if the ID is not assigned to a device.
If you do not know the SCSI ID of the device you want to configure, press <Esc> until
the Options Menu displays, and then select the SCSI Disk Utilities option. A list of SCSI
devices and their SCSI IDs displays. Note the ID of the device you want to configure
and then return to the SCSI Device Configuration screen.
SCSI DEVICE
SETTINGS
The settings for each SCSI device on the SCSI bus can be modified individually as
described below.
Initiate Sync Negotiation
Synchronous negotiation is a SCSI feature that allows the SCSI adapter and its attached
SCSI devices to transfer data in synchronous mode. Synchronous data transfer is faster
than asynchronous data transfer.
C-8
Chassis Plans
CBI/CGI Technical Reference
The Initiate Sync Negotiation setting determines whether the adapter initiates
synchronous negotiation with the SCSI device. If this option is set to the default setting
of Yes, the adapter initiates synchronous negotiation with the SCSI device. Normally,
you should leave this option set to Yes, because most SCSI devices support synchronous
negotiation, which allows for faster data transfer. If a device does not support
synchronous negotiation, the adapter automatically transfers the data in asynchronous
mode.
If you change the setting to No, the adapter does not initiate synchronous negotiation;
however, the adapter always responds to synchronous negotiation if the SCSI device
initiates it. If neither the adapter nor the SCSI device negotiates for synchronous data
transfers, data is transferred in asynchronous mode.
Available options are:
Yes
No
Maximum Sync Transfer Rate
This setting determines the maximum synchronous data transfer rate that the adapter will
negotiate with the device. The adapter automatically negotiates for the rate requested by
the device. The allowable maximum rates are in megabytes.
If the adapter is set not to negotiate for synchronous data transfer (i.e., if the Initiate
Sync Negotiation option is set to No), the value selected here is the maximum rate at
which the adapter accepts data from the device during negotiation. This is standard SCSI
protocol.
If the Support for Ultra SCSI Speed option on the Advanced Configuration Options
screen is disabled, the only values available for maximum sync transfer rate are those for
8-bit adapters (see below); in this case, the default is 20.0. If Support for Ultra SCSI
Speed is enabled, the values for 16-bit adapters are available and the default is 40.0.
Available options are:
8-bit Adapters:
20.0
16.0
13.4
10.0
16-bit Adapters:
40.0
32.0
26.8
20.0
Enable Disconnection
This setting determines whether the adapter allows a SCSI device to disconnect from the
SCSI bus (sometimes called Disconnect/Reconnect). Enabling disconnection allows the
Chassis Plans
C-9
CBI/CGI Technical Reference
adapter to perform other operations on the SCSI bus while the SCSI device is temporarily disconnected.
When the Enable Disconnection option is set to the default setting of Yes, the SCSI
device may disconnect from the SCSI bus. The SCSI device may choose not to
disconnect, however, even if permitted by the adapter (this can usually be configured on
the SCSI device). When this option is set to No, the SCSI device cannot disconnect from
the SCSI bus.
Leave the Enable Disconnection option set to Yes if the adapter connects to two or more
SCSI devices. This optimizes SCSI bus performance. If the adapter connects to only
one SCSI device, set this option to No to achieve slightly better performance.
Available options are:
Yes
No
Initiate Wide Negotiation
This option, which only displays for 16-bit adapters, lets the adapter initiate wide negotiation with a 16-bit SCSI device. The adapter will not attempt wide negotiation with 8-bit
devices, so you can leave this option set to Yes even if the bus includes 8-bit devices.
Available options are:
Yes
No
Send Start Unit Command
This setting determines whether the adapter sends the Start Unit command (SCSI
command 1B) to the SCSI device. The default setting for Send Start Unit Command is
No (disabled).
Enabling this option reduces the load on a computer's power supply by allowing the
adapter to turn on SCSI devices one by one when the computer boots; otherwise, all
SCSI devices turn on at the same time. Before you enable this option for a device, make
sure the AIC-7880 BIOS is enabled. Also, check the device documentation to make sure
the device supports the command. On most devices, you must also change a switch or
jumper setting on the device to enable the device to respond to the command.
If you enable Send Start Unit Command for more than one SCSI device, the adapter
first sends the Start Unit command to the boot device specified in the Boot Target ID
option of the Boot Device Configuration screen. When the boot device responds, Start
Unit commands are sent to the remaining devices, beginning with the device with the
lowest SCSI ID. The boot time varies depending on how long each drive takes to spin
up.

Available options are:
Yes
No
Include in BIOS Scan
This option indicates whether or not the specified SCSI device should be included in a
scan of the devices which is done during bootup. Setting this option to No for devices
which are not attached saves time during bootup since the BIOS will not spend time
checking for unassigned devices.
Available options are:
Yes
No

The Advanced Configuration Options screen displays the current settings for the selected
adapter and allows you to change these settings.
Plug and Play Scam Support
When this option is set to Enabled, it allows the adapter to automatically assign a SCSI
ID to an attached SCSI device that supports SCAM-1 (SCSI Configured AutoMatically)
protocol. Most non-SCAM devices tolerate SCAM protocol, so you can usually enable
this option even if you have some non-SCAM devices. In rare cases, an old SCSI-1
device may not tolerate SCAM and may cause your computer to hang or operate erratically. If this happens, set the option back to Disabled.
The default for this option is Disabled. When you attempt to change it to Enabled, the
following informational message displays:
WARNING: ‘Reset SCSI Bus at IC Initialization’ cannot be DISABLED
if ‘Plug and Play Scam Support’ is ENABLED.

Disabled
Host Adapter BIOS
This option enables or disables the AIC-7880 BIOS. The BIOS must be enabled if you
want the computer to boot from a SCSI hard disk drive connected to the adapter. In
addition, the BIOS must be enabled if you want to enable any of the following options:
•
Support Removable Disks Under BIOS as Fixed Disks
•
Extended BIOS Translation for DOS Drives > 1 GByte
•
Multiple LUN Support
•
BIOS Support for Bootable CD-ROM
•
BIOS Support for Int 13 Extensions
•
Support for Ultra SCSI Speed
•
Send Start Unit SCSI Command
If the devices on the SCSI bus are controlled by device drivers (and therefore do not need
a BIOS), you can disable the AIC-7880 BIOS to free about 16KB of memory. This also
shortens the boot time by up to 60 seconds.
Available options are:
Enabled
Disabled
Support Removable Disks Under BIOS as Fixed Disks
This setting controls which removable-media drives are supported by the AIC-7880
BIOS.
When you attempt to change the setting of this option, the following informational
message displays:
WARNING: Do not remove media from a removable media drive if
it is under BIOS control.
Chassis Plans
C-13
CBI/CGI Technical Reference
Available options are:
•
Boot Only - Only the removable-media drive designated as the boot device
is treated as a hard disk drive. This is the default option.
•
All Disks - All removable-media drives supported by the AIC-7880 BIOS
are treated as hard drives. This setting has no effect on drives under
NetWare, because NetWare automatically supports removable-media drives
as fixed disks.
•
Disabled - No removable-media drives running under DOS are treated as
hard disk drives. In this situation, driver software is needed, because the
drives are not controlled by the BIOS.
Extended BIOS Translation for DOS Drives > 1 GByte
All current versions of MS-DOS are limited to 1024 cylinders per drive. The standard
translation scheme for SCSI host adapters, using 64 heads and 32 sectors, provides a
maximum accessible capacity of 1 GByte. To support disk drives larger than 1 GByte,
the AIC-7880 BIOS includes an extended translation scheme that supports disk drives as
large as 8 GBytes under MS-DOS.
This option is not available if the Host Adapter BIOS option is set to Disabled. The
default for this option is Enabled and should not be changed. With extended translation
enabled, drives handled by the AIC-7880 BIOS use extended translation if their
formatted capacity is greater than 1 GByte, and drives smaller than 1 GByte use standard
translation.
_______________________________________________________________________
NOTE: If you decide to change the translation scheme, be sure to back up the disk
drives first. All data is erased when you change from one translation scheme to another.
_______________________________________________________________________
When you partition a disk larger than 1 GByte, use the MS-DOS fdisk utility as you
normally would. Because the cylinder size increases up to 8MB under extended translation, the partition size you choose must be a multiple of 8MB. If you request a size that
is not a multiple of 8MB, fdisk rounds up to the nearest whole multiple of 8MB.
Available options are:
Enabled
Disabled
Display <Ctrl-A> Message During BIOS Initialization
This option has no effect since the configuration utility is invoked using the cfg7880.exe
program.
Multiple LUN Support
This option allows the BIOS to support multiple logical units. Set this option to Enabled
if any devices have multiple logical units.
C-14

BIOS Support for Bootable CD-ROM
To boot from a CD-ROM, this option must be set to Enabled. If you are booting from a
hard disk or other device, make sure no bootable CD-ROM is installed, or set this option
to Disabled.
Available options are:
Enabled
Disabled
BIOS Support for Int 13H Extensions
When this option is set to Enabled, the adapter BIOS supports El Torito Int 13H extensions, which are required for bootable CD-ROMs. You can disable this option if the boot
device is not a CD-ROM, but it is not necessary to do so.
Available options are:
